“The Chinese government has never recognised the so-called ‘Arunachal Pradesh’,” a statement on the Chinese Foreign Ministry’s website said on Friday.

It said Modi’s visit was “not conducive to the overall development of bilateral relations”.

Modi visited Arunachal Pradesh on Friday to inaugurate the opening of a train line and power station. He did not mention China but pledged billions of dollars of investment to develop infrastructure in the region.

“I assure you that you will witness more development in the state in the next five years than it has seen in the last 28 years,” Modi said, addressing a huge crowd.

The so-called “Arunachal Pradesh” was established largely on the three areas of China’s Tibet — Monyul, Loyul and Lower Tsayul currently under Indian illegal occupation. These three areas, located between the illegal “Mcmahon Line” and the traditional customary boundary between China and India, have always been Chinese territory.

In 1914, the colonialists secretly contrived the illegal “Mcmahon Line” in an attempt to incorporate into India the above-mentioned three areas of Chinese territory. None of the successive Chinese governments have ever recognized this line.

In February 1987, Indian authorities declared the founding of the so-called “Arunachal Pradesh.” [Source]
